Chinese mechanical engineering technology not only has a long history and splendid achievements in Chinese is not only the material culture and social economic development plays an importan

2、t role in the world, and has made great contribution to promote the progress of technology civilization . Machine in the traditional，our country within a long period are leading in the word. In modern times, especially from the early 18th century, to the 19century40s, due to the economic and social

3、and many other reasons, the machinery industry of Chinese was stagnation, but the 100 years is western bourgeois political revolution and industrial revolution time, mechanical science and technology is developing rapidly, and far more than the level of China. So, China mechanical development level

4、and the western gap widens, to the 19th century middle， our country already behind western more than one hundred years. Over the past 40 years, roof bolter of China are developing from nothing, in some places roof bolter were also called anchor rig, the varieties from the original single to variety,

5、 from single power to multiple power. Our country successively has developed a mechanical support leg type electric roof bolter, drill roof bolter, supporting leg and the guide rail type hydraulic pressure roof bolter, supporting leg type pneumatic roof bolter, non-mechanical transmission support le

Such as Wuxi dual-fan production of YG-80, Chengdu Hamma production of YXZ-70, Chongqing prospecting plant production of MGJ-50 etc Holing main technology is double eccentric, commonly used in drill pipe is73, 89, according to d

11、ifferent design of jacket tube drill pipe commonly use108, 127, 146 etc specifications. They need to be equipped with proper air compressor to driven impact power, because the bottom of impact always role in the hole, so often be called as blow. Anti-floating anchor, excavation, soil nail wall suppo

12、rt are widely used in workers of the construction process. But they are moving heavy, function single, and increased with the processing costs, much higher and higher buildings, this kind of type has been unable to meet the needs of the market. So anchor bolt drill and tracked automatically walking

13、got quickly development. In the domestic there are many types of the crawler roof bolter, which features in the main power head adopts the high torque motor drive, speed range usually is variable speed. They are greatly improving the rig performance. The track is driven by a hydraulic motor, which m

14、ade the drilling machine more flexibility and reduces the complex of the artificial joint. This type of drill also adopted the attack mode, such as the Oriental industrial production of DF-3000, Xuanhua Ingersoll-Rand production of CM-351. This type of drill same with the slide drill on the pulling

15、sleeve also need be equipped with auxiliary equipment and other auxiliary equipment. In China there is a kind of double anchor rig power head roof bolter, characteristic of this kind of drill rig is drill pipe and casing are driven rotation by each power head, and do not influence each other, pull c

16、asing can be done automatically by the machine.Every rig all have they own operation manual. The follow is MDL-50A Drilling Rig operation manual. 1. PrefaceThe company has adopted its latest assembling technology for all main parts and components of this product. And the rig is completed with chassi

17、s for pretrial and pipe wrench and other accessories, which the re-designed fully new hydraulic system incorporates into one entity. Key elements are all renowned brands either local or imported, and are fully hydraulically controlled and displayed through instruments. The drilling rig is easy and f

18、lexible of operation and has high working efficiency and so well meets the requirements by the customer.MDL-50A Drilling Rig is a new type fully hydraulic long-stroke anchored drilling-rig for engineering purposes developed and manufactured by Jiangsu Wuxi Mineral Exploration Machinery General Facto

19、ry Co. LTD (formerly Jiangsu Wuxi Mineral Exploration Machinery General Factory). MDL-50A Drilling Rig is a hydraulically controlled, anchored power head engineering drill. Its overall weight is under 4000kg, is mainly for the anchoring engineering of coast and dangerous rock/cliff mass for geologic

20、al disaster prevention activity, and the anchoring engineering of rock body etc to control displacement of buildings, and also for supporting of deep-foundation pit and groundwork reinforcing engineering in urban construction site, for blowing up engineering or blowing up hole etc. But the Drilling

21、Rig isnt suitable for anchoring engineering of high-edge slope or dangerous rock body. MDL-50A Drilling Rig possesses the characteristics of stable performance, high working efficiency, multiply usage, as well as the capability of drilling sophisticated stratum and handling accidents etc. This drill

22、ing rig, deployed by common alloy drill tools or other drill tools, can perform revolving-and-drilling. In the rigid rock stratum, the drilling rig deploys the spheroid drill bit to perform striking and revolving and drilling to have high-speed-bored hole; if deployed with air-compressor and pneumat

Structure of the Drilling RigMDL-50A drilling rig comprises of the following main components:（1）The power assemblyThe power module is made up of three electric motors which respectively drive three

29、sets of pumps. Among them, one group is a double gear pump. The big one is responsible for drilling quickly of the drill; and the small one is responsible for the movement and the support of one side of crutch as well as the medium-speed, low-speed drilling. One set of pump is responsible for the mo

30、vement and the support of another side of crutch and the medium-speed drilling as well as the quickly lift of the power head. The last set of pump is responsible for the rise of the tower. When you start operating the drill, you should notice the rotated direction of three electric motors, its turni

31、ng should be identical with the red arrow on the pump or the back shell of the motors, or the drill cant work normally.（2）The power head assemblyPower head of MDL-50A type drilling rig is driven by Double hydraulic motor through gear box transmission and speed regulating, and it drives the main shaf

32、t and fore end drilling rod connection to turn in positive/reverse directions, thereby driving the drilling bits below.In the power head box is stored gear oil. When in operation be sure to check the oil level from time to time to see there is sufficient oil. On the side of the box is fitted an oil level threaded plug. Just by raising the mast to vertical position and loosening the oil level screw you can check the oil level.The up/down motion of the power head is effected by the roller assembly beneath it, which is driven by the chains. After the drilling rig has worked for a period of
